You can use procreate to make a webtoon on an iPad but ibispaint is a great free app alternative with comic specific features!
Now the format that LINE webtoon specifically requires for you to upload onto their site is for your webtoon size to be 800 x 1280.
Some people have had issues with being unable to change their canvas size of their webtoon within procreate.
Also if you want to make 3D model backgrounds for your webtoon then you can use browser base programs like Clara.io and Sketchup on both your desktop and mobile tablet~
If you’re looking for 3D webtoon backgrounds to use that are already made then I definitely recommend ACON3D because they have a lot of backgrounds that other Webtoon artist use~
I’ve covered some of my favorite free art apps to use on the desktop in a previous blog post here along with some beginner friendly webcomic tools as well~
Can I post my webtoon with a mobile device?
In order to be able to post a webtoon with your mobile device like your phone or iPad you need to make sure you request the desktop site version of the site so you can upload it that way.
Here is a link to a blog post where I go into more detail on how to do that but you can totally post your webtoon with a mobile device!
